The answer is 48 because you have to do is 21 x 4 which is 48
Answer:
The expression is not factorable
A scale factor of less than one will shrink a figure. A scale factor more than one will enlarge a figure. A scale factor of one will keep the figure the same.
Shrink, enlarge, same
Find the number that both can be divided by i.e. the common denominator of 56/8 is 8 because 56 is divisible by 8 and 8 is also divisible by 8.
so by finding the common denominator and dividing the fraction, the equation would look like this: 7/1
BAD=BCD(base angle ,isosceles triangle)
ABD=CBD(given)
BAD+BCD+ABC=180(angle sum of triangle)
36+36+ABC=180
ABC=108
ABC=ABD+CBD
CBD=108/2
=54
therefore
x=54
